Summary

The new Mercedes-Benz 4,6l bi-turbo engine M 278 was generated as a member of a new high performed engine family of v6 and v8-engines, replacing the very successful 5.5l predecessor engine M 273. This engine is part of a modular conception and offers an exclusive driving performance as well as a fuel economy that up to now was more typical for 6-cylinder engines. It is based on a high-graded technology portfolio that contains direct injection of the 3rd generation, the Mercedes-Benz start-stop-system, heat management and pressure-controlled oil circulation as fundamental devices. Compared with the even today very successful predecessor, power was increased by 12%, torque by 32% and the fuel consumption was reduced by more than 10%. The sustainability of this engine is ensured because of the modular concept.
